Description
Customizable Inner Diameter Toroidal Core for Power Cables, Signal Lines and Flat Ribbon Cables
Professional EMI Suppression Core Solution
Advanced Ni-Zn ferrite core engineered for superior signal integrity and EMC compliance with REACH certification, designed for OEMs and System Integrators.
Product Overview
The T Type Toroidal Ferrite Core from Hangzhou Careful (Careful Magnetism Co., Ltd.) is a high-performance EMI/RFI suppression component. The toroidal closed magnetic circuit design represents the optimal shape for magnetic induction, delivering the highest inductance per turn (AL factor) and providing superior common-mode and differential-mode noise suppression performance.
Material Options & Specifications
  • Available in premium Ni-Zn or Mn-Zn ferrite materials
  • Ni-Zn material offers excellent high-frequency characteristics, particularly suitable for noise suppression in the 1MHz-500MHz frequency range, with peak impedance reaching several hundred ohms
  • Mn-Zn material features higher permeability, performing better in lower frequency bands (1kHz-10MHz)
  • Specifications expressed as "T Outer Diameter × Inner Diameter × Height" (e.g., T9×3×5 and T22.5×20×13.8)
  • Inner diameters range from 3mm to over 20mm, accommodating various cable types from thin signal lines to thick power cables
Installation & Operation
Toroidal cores are installed by directly threading cables through the center hole—no tools required. When higher impedance is needed, multiple turns of the cable through the core can be applied; more turns result in higher impedance. The core operates across a wide temperature range of -40°C to +125°C.
Certifications & Compliance
Fully compliant with RoHS, REACH, and ISO 9001:2015, offering reliable quality and environmental responsibility.
Applications
  • Communication equipment (power and signal lines in servers, switches, routers, etc.)
  • Switching power supplies and variable frequency drives
  • EMC design for high-power electronic devices such as motor drives
  • Medical electronic equipment
  • Industrial automation control systems
  • Automotive electronics and EV charging modules
  • Consumer electronics (phone charging cables, data cables, USB extension cables)
As a core component of EMI common-mode chokes, the T Type toroidal core provides engineers with a reliable electromagnetic compatibility solution through efficient noise suppression and flexible installation.
